I just bought my first home and the seller's painted all the trim and door with latex paint over a high gloss paint without using a primer. Now you can bump into a door and the latex paint scrapes off. Is there a product that will penetrate the latex and bond to the gloss underneath. Then I could paint over that?? I can't even begin to think of having to sand every piece of trim and door in the place. I'm a city bred girl and use to a superintendent doing all the repairs in my home....now I'm on my own...gulp!! HELP!
